What’s Driving Frequency Extensions?
• DOCSIS 3.1 offers >1Gbps speeds, enables spectrum usage to 200 MHz in
return, and 1,200 MHz (1,800) in forward
• OFDM signal can be 192 MHz wide, and multiple signals
• Expanding return band to improve speeds can squeeze forward band if not
expanded at the same time

Testing Plant frequency Extensions
• Need to verify amplitude vs frequency response of extended frequency range
• Inserting test signal is inadequate, as it only tests one frequency
- Can’t assume other frequencies have same performance
- Must have meter or analyzer that reads test frequency
• Contractor constructing the extension must certify performance
• Maintenance techs need up-to-date tools to maintain and troubleshoot
upgraded plant issues
• Built-in switchable diplexers are very important

DOCSIS 3.1 – Sweeping for maximum benefit
• Test DOCSIS 3.1 signal physical performance and service (IP) quality
- Measure OFDM signal level, MER, check ingress under carrier
- Check for codeword errors, verify profiles lock and no uncorrectable codeword
errors
• Verify network RF transmission performance by sweeping
- Adding OFDM signals, typically at higher frequencies
- Some extending frequency range of upstream and downstream
- Need to optimize performance to obtain optimum efficiency
• RF Amplifiers still must operate within linear transfer range
- Levels too low result in low MER, CN – unable to achieve higher order QAM
- Levels too high result in intermodulation noise and distortion – again, unable to
achieve higher order QAM
